ArcEngine/Java issue

ArcEngine 10.1 needs Java to be installed and ArcEgine finds Java by registry keys (not by environmental variables like JAVA_HOME and PATH).

When ArcEngine does not found Java properly there are two different error messages in the console log after Synchronized with "xxx" Map

1 Java Executable

 Loading jawt.dll failed. This is normal if java.version < 1.3. If java.version is > 1.4 and if this failure has occurred on Windows,

please ensure that this program is started with a Java executable from a JDK/JRE install location on this computer.

2 Java HotSpot

How to fix the it

1 Install the Java that is included in the IMSMA^NG installation package

2 If Java already was installed;

2A verify Java version by in the Command window type Java -version and click Enter.

2B Verify that the environment variable JAVA_HOME is set to C:\Program Files\Java\jre7 on 32-bits OS or C:\Program Files (x86)\Java\jre7 on 64-bits OS.

3 If none of the above fixed the problem, add ;%JAVA_HOME%\bin to the end of the PATH environment variable.
